    Organic Modification of Titanium Dioxide and Its Influence on the Properties of Engineering Plastics

    What is Titanium Dioxide exactly?

    Titanium dioxide is an important organic chemical pigment. Its main component is titanium dioxide. Two process methods are used to make titanium dioxide. One is the sulfuric acid process and one is the chlorination process. It's used extensively in coatings.

    The performance of engineering plastics depends on many factors.

    The defects in titanium dioxide, as well as the strong polarity of the surface, make titanium dioxide easy to absorb water. It is also easy to agglomerate and agglomerate during storage, production, and transport. This limits its use in organic polymers. The key to wide-ranging use of titanium dioxide is surface modification to increase its dispersibility and compatibility in organic polymers. It is necessary to perform organic modification in order to improve the wetting, dispersion, and rheological characteristics of titanium dioxide in different dispersion media.


    1. The Lab value of titanium dioxide powder is not affected by the use of polysiloxane, polysiloxane, or polyol organic modifier to treat it. However, oil absorption indexes of the product are reduced.


    2. The titanium dioxide that has been treated with polysiloxane is hydrophobic, which increases its compatibility with plastics resins.


    3. Polyols modified titanium dioxide are hydrophilic. They absorb moisture easily, which can affect the plastics' application performance.


    4. In ABS resin systems, titanium dioxide is treated with polysiloxane. This has the most impact on the mechanical characteristics of plastic products. The material's tensile strength and impact resistance are also the best.


    5. To enhance the material's overall performance, it is recommended to modify titanium dioxide in engineering plastics by using polysiloxane modifiers. Additionally, organic modifiers that contain different groups should be chosen according to the different applications.

    Bismuth Hydroxide and Organic Matter Interactions

    Bismuth hydroxide is a non-toxic bismuth compound used in many pharmaceuticals and in bacterial resistance studies. It is widely used in antidiarrheal medications, especially for oral use. It also is used as an adjuvant for chemotherapy in a range of cancers.

    Biologically, bismuth is a highly stable and non-toxic metal that is next to lead in the periodic table. It has a low melting point and is resistant to the toxic effects of chlorine and iodine.

    It is a hard, brittle, reddish-colored metal that is in oxidation state +3 when in solid form. It dissolves in nitric acid and in hot sulfuric acid. It can be reacted with halogens to form bismuthine, BiH3, which is an endothermic compound that has a low boiling point of 17@C (62.6@F).

    Bismuth oxidizes to bismuth subnitrate in acidic medium (H2SO4), but it does not dissolve in the neutral pH of water and should be dissolved with an acid such as citrate buffer solution or NaOH. It does not bind to natural organic matter and is generally inert.

    We investigated the interactions of bismuth and natural organic soil material using a combination of batch equilibration experiments and EXAFS spectroscopy. The results indicate that the equilibration of bismuth with organic matter is a complexation reaction and involves a cationic ion competing with the metal for the complexation sites in the aqueous phase. Our data support the use of geochemical models such as WHAM-Model VII, NICA-Donnan and SHM to predict metal binding kinetics in organic soils.
